S+DOX is a Spotfire S+ library used in the design and analysis of fractional
factorial, response surface, and robust (Taguchi) designs.

The library strongly emphasizes graphical displays for exploring and
analyzing experimental data. It uses new methodology for estimating
standard errors in saturated models, and enabling better assessment of
important experimental factors.

The response surface functions provide an easy analysis and display of
response surfaces with contour, image, and surface plots.

The robust design functions provide designs for control and noise
factors, and allows calculation and analysis of signal to noise ratios
and other responses. The analysis identifies factors that enable
the process to be optimized with minimal sensitivity to noise.

Some primary functions of the module are:

design.digest   fac.aov 
rsm.design  rsm.lm            
robust.design   robust.sn
pareto      tfiplot
acplot      ebplot
